Detailed Description

Enumeration Type Documentation

subproc_flags

enum subproc_flags

Enumerator
SUBPROC_NORMAL	Default subprocess flags.
SUBPROC_WARN	Emit a warning instead of an error.
SUBPROC_NOPIPE	Ignore SIGPIPE, and make it return 0.
SUBPROC_NOCHECK	Do not check the subprocess status.
SUBPROC_RETERROR	Do not emit errors, just return the exit status.
SUBPROC_RETSIGNO	Do not emit errors, just return the signal number.
